Re: dwarven agriculture
Given how often the bulk of their civilizations are depicted as mountain/subterranean-centric, beer- or for that matter, most spirits- wouldn’t seem like it’s a product they’d invent. Breads would be problematic as well.
Why?
Because most grains aren’t easily grown on mountainsides. (Or in caves, for that matter.)
Rice and grapes, OTOH, can be and often are. Mountains and hills covered with vineyards and terraced gardens with sophisticated irrigation systems might be a hallmark of entering dwarven lands. Potatoes and other root vegetables would be important, too.
So while dwarves may appreciate beers, ales and bread, and even MAKE those, the supplies for making them would largely be acquired via trade.
Beverages like sake, wine and vodka, OTOH, would be right up their alley. Ditto things made from fermented mushrooms. And some of THOSE might be psychoactive. Possibly even DEADLY to other races. Cue “Purple Haze”.
